Recommendations: Collectibles (Fish, Birds, Books etc) by SiTheGreat

I like being able to fill out collections of items, so I've compiled various mods that add additional collectibles to SDV. Some of these collections even add new mechanics to the game!

Birds

• Ornithologist's Guild adds a mechanic where you can observe birds using binoculars. Those birds are then added to your Life List. Additional bird packs for this mod are listed on the modpage.

Books

• Button's Extra Books adds additional power books to the game.
• More Books adds additional power books to the game.
• Book Collecting (SNF) adds non-power books that can be collected and viewed in the Secret Notes tab in the menu. Additional book packs for this mod are listed on the modpage.

Bugs

• Nature in the Valley adds a mechanic where you can collect bugs, leaves, and small critters using a bug-catching net. Those creatures are then added to the Insectarium. Additional creature packs for this mod are listed on the modpage.
